General annotation (Comments)

Function

Ligates lysine onto the cytidine present at position 34 of the AUA codon-specific tRNA(Ile) that contains the anticodon CAU, in an ATP-dependent manner. Cytidine is converted to lysidine, thus changing the amino acid specificity of the tRNA from methionine to isoleucine. This enzyme is essential for viability. HAMAP MF_01161

Subcellular location

Cytoplasm Probable.

Domain

The N-terminal region contains the highly conserved SGGXDS motif, predicted to be a P-loop motif involved in ATP binding. HAMAP MF_01161

Sequence similarities

Belongs to the tRNA(Ile)-lysidine synthase family.
